CHRISTIAN WAIS, 0F NEWVPORT, KENTUCKY.

GRAIN-METER.

SPECIFICATION forming part of Letters Patent No. 244,006, dated July 5, 1881.

Application filed February 1, 1881. (No model.)

To all whom it may concern:

' Be it known that I, CHRISTIAN WAIS, a citizen of the United States, of Newport, in the county of Campbell and State of Kentucky, have invented certain new and useful Improvements in Automatic Grain-VVeighers, of which the following is a specification.

This invention relates to improvements in that class of automatic grain weighing machines in which a weighing-box contains rotating buckets and is suspended from a steelyard, the buckets receiving the grain successively, and when a certain quantity has been received in one compartment it is discharged by being disengaged through the depressed position of the steelyard, while at the same time the supply of grain is automatically out off until another compartment is presented for filling.

My invention consists in certain novel constructions and arrangements of parts, which will be fully hereinafter described in detail, and specifically pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation of my improvement. Fig. 2 is a central cross-section of the bucket-cylinder. Fig. 3 is a front elevation. Fig. 4 is a central vertical section of the bucket-cylinder and tripping devices. Fig. 5is an end elevation of the grain-spout and cut-0d valve. Fig. 6 is a cross-section on line y y, Fig. 5. Fig. 7 is a plan view of the bucket-stop. Fig. Sis a perspective view of one of the bucket-tops. Fig. 9 is a plan view of the counterbalance-weight and lever, tripping -lever, grain -spout, and valve. Fig. 10 is an elevation of the counterbalance and guide, the balance being in section.

A A represent the frame of the machine, on which my improvements are mounted.

B represents a box, into which the grain is dumped as it is weighed off by the scales.

Orepresents a series of buckets attached between two disks, O, which are mounted and turned on axial bearings o c.

d represents a circular plate placed on the outer surface of the disks 0, within a circular flange, d.

(1 represents notches inthe periphery of plates d. One notch is placed opposite each division of the revolving measure or bucket, into which notches a pin, 0, is made to enter and stop or hold the measure in position.

D represents suspension-rods attached at the upper end by knife-bearings to crank-ar1ns D, which constitute the shorter end of the scalebeam F.

E represents a bracket-guide, which is attached rigidly to the frame A. The rods D D pass through perforations in the guide-brackets E E, by which said rods are maintained nearly in a vertical plane. The journal-boxes c are affixed rigidly to rods D, and rise and fall with them,carryin g also the rotatin g measure 0 G.

E represents a cross-rail on the frame of the machine.

0 represents a rigid arm attached to rail E. v 6 represents a pin entering groove d. When disks 0 with the measures are empty the notches d are in engagement with stud or pin 6, and the measures are held stationary under the grain-spout.

F represents a weighted scale-beam hung on knife-pivots f in the usual manner.

F represents the poise sliding on scale-beam F. Poise F is adjusted so that when one of the compartments 0 is filled the beam F rises, rods D are dropped, and notches (1 are dropped below the studs or pins 0, and the disks 0 are free to move, which the weight of the article in the filled compartment 0 causes them to do, and the measure is emptied.

H represents a secondary weighted lever hung on knife-bearings h, which bearings are rigidly attached to a cross-piece, P, on the frame A of the machine. The secondary weighted lever H is provided with arms h h which are permanently connected by pivots with the cut-off valve I.

J represents a grain-spout.

I represents a valve or cut-oft, which slides in grooves in the end of the grain-spout. As the scale-beamFrises it strikes the end of lever H and raises the latter, and cut-off I is lowered and the grain-spout is closed in the act of emptying the compartments 0. When the long arm of the scale-beam F is depressed the weight H on the secondary lever H serves to depress the latter, and thereby raise the cutoff valve to permit the passage of the grain to the succeeding compartment of the rotary buckets.

K represents a stop for the end of the lever F, to prevent its rising and falling too far.

M represents a device for registering the Weights of grain measured by the revolution of disks 0.

0 represents a cam on one of the disks 0.

N is a stem of the register M. When the cam O raises the stem the register is moved. This movement occurs with each revolution of the disks.

I claim- 1. In a grain-weighing apparatus, the pivoted lever H, permanently connected at one end with the vertically-sliding cutoff valve I of the spout J, in combination with the scalebeam F, having arms D D, and the vertical rods D D, suspended from the said arms and provided at their lower ends with the rotary buckets, all substantially as described.

2. In a grain-weighing apparatus, the pivoted lever H, having the arms h h permanently connected with and operating the vertically-sliding cutoff valve Iof the spout J, in combination with the scale-beam F, having arms D D, the rodsD D, suspended from the arms, the rotating buckets supported by the lower ends of the said rods, and guide-brackets E, guiding the movements of the latter, substantially as described.

3. The rods D D, suspended at their upper ends from the arms D D of the scale-beam F, and carrying at their lower ends the rotating buckets O, in combination with the plates attached to the ends of the buckets, and provided with the notches d, and the arms 0 0, attached to the cross-rails E, and provided with the laterally-projecting pins e and c, substantially as and for the purpose described.

4. The horizontal lever H, pivoted intermediate ot'its length above the scale-beam, the forward horizontal end portion of said lever being connected to the vertically-sliding cutoff valve of the grain-spout, and the rear horizontal end portion being weighted and arranged in the path of the scale-beam, butdisconnected therefrom, substantially as and for the purpose described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

CHRISTIAN WAIS.
